Brian's Application Notes: The factory includes a sheet like this between the top of the factory shock mounts and the car to cut noise, and that sheet should be transferred over to any coilover you install. These sheets go between the coilover spring and spring perch and further cut noise potential. Be sure to know the diameter you need for your coilovers.
